Mobile parking app for professionals
I evaluated an end-to-end mobile parking flow with professional drivers and exposed comprehension gaps that broad usability scores alone would have missed.
The research question
Could professional drivers complete the full parking flow without guidance, and which moments needed redesign before the next iteration?
The evaluation followed the real sequence from entering the product and creating an account to finding a space, checking in and checking out. This kept individual screen issues connected to the job the service needed to support.
How I approached it
From question to evidence
- 01 / Frame
Connect the product questions to the work context
I combined a heuristic review with an initial account of drivers’ routines, needs and parking constraints.
- 02 / Observe
Test the complete flow through realistic tasks
Five professional drivers completed the core journey while thinking aloud, followed by a structured questionnaire and debrief.
- 03 / Prioritise
Separate broad ease of use from local breakdowns
I mapped errors, hesitations and explanations to each step, then prioritised changes by their effect on task completion and confidence.
How I organised the evidence
Positive overall usability with specific comprehension failures
Participants saw clear value in the service, but screen-level evidence showed several actions and terms that were not self-explanatory.
- 01
Observed flow
Where people hesitated or chose the wrong action
Account creation, address entry and unfamiliar action icons created friction despite an otherwise learnable flow.
- 02
Comprehension
Where labels and status cues needed context
Dots, scan-based check-in and domain-specific terminology required clearer explanations or more familiar wording.
- 03
Perceived value
Why the service mattered in daily work
Participants connected the service to finding spaces more quickly, reducing wasted time and avoiding disruption to deliveries.
What I delivered
A task-level redesign brief grounded in professional use
I delivered a persona and journey synthesis, screen-by-screen findings and a focused set of recommendations covering visibility, terminology, onboarding and action feedback.
